• Zeroth Law

• First Law

• Second Law

• Third Law

What is the main concept described by the Zeroth Law of Thermodynamics?

• Conservation of energy

According to the Third Law of Thermodynamics, what happens to the entropy of a perfect crystal as the temperature approaches absolute zero?

• It increases

• It decreases

• It becomes zero

• It becomes infinite

If two objects, A and B, are each in thermal equilibrium with a third object, C, what can be said about the relationship between A and B according to the Zeroth Law?

• A and B are not related

• A and B are in thermal equilibrium with each other

• A and B have different temperatures

• A and B exchange heat

Which of the following best describes entropy in the context of the Second Law of Thermodynamics?

• A measure of pressure

What is the temperature at which the entropy of a perfect crystal is exactly zero, according to the Third Law of Thermodynamics?

If a system is isolated and no energy is transferred in or out, what does the First Law of Thermodynamics predict about the system's internal energy?

• It increases

• It decreases

• It remains constant

• It becomes zero
